Commenting on joining Sussex, McAndrew said: "I can't wait to get to England to play with Sussex, I thoroughly enjoyed my time in county cricket last year and I am looking forward to taking the next step in my career playing red and white-ball cricket this season.
"I look forward to teaming back up with Paul Farbrace and contributing to Sussex's success."
Bowling coach, James Kirtley, said: "The squad are really looking forward to welcoming Nathan to the group. Nathan is more than a capable batter, but it will be his bowling that will excite us.
"In T20 cricket he regularly bowls the pressure overs which takes courage and skill. For our T20 team to know we have someone who can be relied upon in these situations is very comforting.
"In four-day cricket he runs in all day. His experience in England last year will pay dividends as his performances got better and better.
"It shows he can adapt and is willing to learn and coupled with a bowling engine, I am sure Nathan will be successful at Sussex."
